Hi, Spice tower, windmill missing (two tubular protrusions close to the top). Not too old with millesimal fineness. Cannot recognize marks, to be honest not even London import mark. Cheers
Pseudo/fantasy marks, and not that old, made turn of the 19th century. Please check for other small but proper Dutch (hall)marks. for more information see: viewtopic.php?f=5&t=32028 and viewtopic.php?f=5&t=28590
